If you are looking to buy in PA, its possible you can qualify for PHA KFIT program that gives you a 5% closing cost forgivable loan.

They are a bit undersized but perfectly suitable for 1 bedroom apartments and the slight increase in costs is far less than the costs associated with venting the units properly.

Pretty reasonable cost too. 

Another good thing about that is that you can do a cost segregation study based on the percentage of the house that is being rented to your house mates.

Would you rather set it and forget it and not need to refi again or rather take advantage of low/no closing costs on this loan and plan to be more aggressive on your rate at the time of your refi?

But you have closing costs for Refi, and sale, but in sale you get all your equity back out. 

But again, your profit after selling costs (and any capex improvements) would have to be in excess of $60ok to really make sense.

You can avoid costly mistakes. 

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

It costs me $1,500 to evict a tenant with it usually taking two-three months.
